About Naked evening primrose

Oenothera nuda, commonly known as Naked Evening Primrose, is an annual or biennial herbaceous plant distinguished by its vibrant yellow flowers that open at dusk and last until the following morning. It's ideal for wild-style gardens, rockeries, or borders where a splash of color and nocturnal interest are desired. Its upright habit and delicate blooms make it very attractive in any sunny spot.

Care tips

This evening primrose thrives in full sun exposure for abundant flowering. It tolerates drought well once established, so watering should be moderate, allowing the substrate to dry out between waterings. It prospers in well-drained soils, even poor or sandy ones; waterlogging is its main enemy. Avoid over-fertilization, as it can promote leaf growth at the expense of flowering.
